REAR SIGHT FOR GUNS.

SPECIFICATION forming part of Letters Patent No. 666,665, dated January29, 1901.

' Application filed October 10, 1900. Berial No. 32,596. (No model.)

To all whom, it may concern:

Be it known that I, CHARLES H. GRIFFITH, of New Haven, in the county ofNew Haven and State of Connecticut, have invented a new Improvement inRear Sights for Guns; and I do hereby declare the following, when takenin connection with the accompanying drawings and the letters ofreference marked thereon, to be a full, clear, and exact descrip- IOtion of the same, and which said drawings constitute part of thisspecification, and represent, in

Figure 1, a plan view of one form which a sight constructed inaccordance with my'i'n- I5 vention may assume; Fig. 2, a side viewthereof; Fig. 3, a sectional view showing the application of my improvedsightto a gunbarrel; Fig. 4, a corresponding View showing theapplication of my improved sight to an octagonal gun-barrel to which thesight is conformed in shape; Fig. 5, a broken view in centrallongitudinal section, showing one mode of securing my improved sight toa gun barrel; Fig. 6, a corresponding view showing a different Way ofsecuring the sight to a gun-barrel.

My invention relates to an improved rear sight forguns, the object beingto produce an extremely simple, easily-adjustable, convenient, andeffective sight constructed with particular reference to fewness ofparts and cheapness of manufacture.

WVith these ends in View my invention consists in a sight having certaindetails of con- 3 5 struction and combinations of parts, as Will behereinafter described, and pointed out in the claims. I

In carrying out my invention I strike up from a suitable sheet metalblank a sightbody comprising a yielding shank A, a horn A, and a head AThe said head A is made integral with and located at the forward end ofthe said shank and formed with a centrally-arranged and threadedscrewehole B and provided upon its opposite edges with two downwardlyturned retainingflanges C and D, extending parallel With each other andwiththe longitudinal axis of the said shank. If desired, one of theseflanges may These flanges perform the function of clasping thegun-barrel, to which therefore they should by preference be conformed incross-sectional shape. If the barrel is a circular barrel, the head andflanges will be bent to conform thereto, as shown in Fig. 3, while ifthe barrel is an octagonal barrel the flanges and head will be bent toconform thereto, as shown in Fig. 4. The screw-hole B before mentionedreceives the shank E of a short screw, the beveled head F of which isconstructed in the pitch of its bevel to fit tightly into a dovetailedor undercut slot G, formed transversely in the top of the gun-barrel H.

In securing a sight-body to the gun-barrel the beveled head of the screwis introduced into the slot G from one end thereof and moved into thelongitudinal center of the slot. The said sight-body is then placed uponthe gun-barrel and the screw-hole B brought into alinement with theshank of the screw. A screw-d river is now inserted into a slot 6,formed in the shank E of the screw,after which the screw is turned, soas to draw the head of the sight-body down firmly upon the gun-barrel,the sides of which are clasped by the retaining-flanges of the head. Thescrew is of course kept by the bevel of its head from lifting out of theslot, in which, however, it is freeto turn. The horn A aforesaid isformed at and integral with the rear end of the shank A of thesight-body and contains the usual V-shaped sight-notch I, terminating ina small sight-hole J. This notch is raised or lowered 8 according to therequirements of the user of the arm by means of a small adjusting-screwK, mounted in a small threaded opening L, formed in the extreme rear endof the shank A and therefore at a point directly in front 0 of the hornA, which protects it. The lower end of this screw impinges upon the topof the gun-barre1, which constitutes a point of purchase for lifting thehorn A by springing the shank A when required. 9 By providing myimproved sights with screws like the screw E, I may apply them to gunsprimarily constructed for the reception of ordinary sights and theretoadapted by forming their barrels with transversely-ar- I00 rangeddovetailed slots for the reception of dovetailed ribs formed at theforward ends barrel 0.

of the sights. It is apparent, however, that my improved sight may beattached in other and still cheaper ways-as, for instance, as shown inFig. 6 of the drawings, in which the sight-body has a shank A, a horn A,and

a head A having retaining-flanges O andv D, and therefore correspondingto the sightbody shown in the other figures of the drawings; but thissight-body is secured in place by a simple screw M, passing downwardthrough its head A and into an ordinary threaded screw-hole N, formed inthe gun I would therefore have it understood that I do not limit myselfto the exact construction herein shown and described, but hold myself atliberty to make such changes and alterations as fairly fall within thespirit and scope of my invention.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a rear sight forguns, the combination with a sight-body formedfrom a single piece of sheet metal and having a shank, an upturned hornlocated at the rear end thereof, and a head located at the forward endof the shank and having a downwardly-turned retaming-flange forclaspingthe gun-barrel; of means for connecting the sight-body through its headto the gun-barrel, and means applied to the rear end of the said shankof the sightbody for vertically adjusting the said horn.

2. In a rear sight forguns, the combination with a sight-body formedfrom a single piece of sheet metal and having a shank, an upturned hornlocated at the rear end thereof, and a head located at the forward endof the shank, formed with a screw-hole and having a downwardly turnedretaining flange for clasping the gun-barrel; of a screw havinga shortshank adapted to enter the said screwhole and formed witha beveled headadapted to be entered into a transversely-arranged dovetailed slotformed in the gun-barrel.

3. In a rear sightforguns, thecombination with a sight-body formed froma single piece of sheet metal, having ashank, an upturned horn locatedat the rear end thereof, and a head located at the forward end of thesaid shank, formed with a threaded screw-hole, and having twodownwardly-bent retainingflanges for vlasping the gun-barrel, to theshape of which they are conformed, of a screw having a short shankadapted to enter the said screw-hole, and formed with a beveled headadapted to be entered into a transverselyarranged dovetail slot formedin the gun-barre], and an adjusting-screw mounted in the said shank justin front of the said horn, and impinged upon the gun-barrel forspringing the shank and vertically adjusting the horn.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.

CHARLES H. GRIFFITH.
